Description
Technical field
The present invention relates to laser weld appearance of weld control technology, be particularly related to a kind of laser penetration welding seam formation control method for Hass alloy conductive roller, be specially adapted to the I type groove heavy wall Haas alloy material laser weld of making for the conductive rollers of Automobile Plate electrogalvanizing unit.
Background technology
Haas alloy is mainly used the argon tungsten-arc welding (GTAW weldering) that fills silk; for conventional GTAW (GTAW) bottoming of thicker sheet material; the method welding of manual electric arc welding (SMAW) capping, also can adopt the method welding such as welding (GMAW), Lincoln weld (SAW).
In prior art, there is document 1 to disclose " The welding metallurgy of HASTELLOY alloys C-4C-22 and C-267 ", adopt GTAW method welding C-4, C-22 and C-267, the fire check sensitiveness of research material; In document 2 " Hastelloy C-22 alloy ", introduced conventional welding method: the GTAW/GMAW/SAW of several Haas alloys; Wherein because SAW heat input is too high, recommendation not; In document 3 " welding of Haas corrosion-resisant alloy ", recommend the above Haas alloy of thickness 2mm to adopt bevel GTAW, GMAW and SMAW Welding Process Design.
The main GTAW method that adopts of visible Haas alloy welding, 3mm needs bevel above, adopts multi-pass welding, must cause welding heat affected zone (HAZ) wide, and welding residual stress is large; Next adopts multi-pass welding, and weld seam is easy to form pore, is mingled with, incomplete fusion defect; To weld seam, add filling metal, may cause forming again low-melting compound, bring out HOT CRACK FOR WELDING P, reduce weld seam decay resistance.
Summary of the invention
The object of this invention is to provide a kind of laser penetration welding seam formation control method for Hass alloy conductive roller, in the conductive rollers manufacture craft of Automobile Plate electrogalvanizing unit, solve a difficult problem for Haas alloy welding, guarantee the service property (quality) of conductive rollers.
For achieving the above object, technical scheme of the present invention is,
A laser penetration welding seam formation control method for Hass alloy conductive roller, carries out cylindrical shell with Haas alloy-steel plate round as a ball, and the sheet edge of round as a ball front banjo fixing butt jointing is processed to the groove of certain angle, and the abutment joint after round as a ball forms I type groove; Cylindrical shell after round as a ball completes joint assembling on fixture; Laser weld is shaped to control and adopts air cooling-copper lining to control back of weld shaping, and the abutment joint back side is pressed on air cooling-copper lining, processes air drain and the protection vent hole of controlling weld shape on copper lining; Before laser weld, to air cooling-copper lining, lead in advance protective gas, drive air, in welding process, remain to copper lining and pass into high-purity Ar gas, Ar atmospheric pressure 1-2kg, concentration 90-95%; Carry out laser beam and the adjusting of seaming position centering, torch height and measure and regulate, laser weld setting parameter etc., then carry out abutment joint laser tack welding; In welding process, the complete burn through welding of laser beam, forms molten hole, realizes and once welds two-sides forming.
Above-mentioned welding two-sides forming can adopt conventional laser welding process.
Further, laser penetration weldering two-sides forming of the present invention is controlled, and the weld seam starting point at banjo fixing butt jointing two ends adds lead-in plate and terminal adds end tab, and weld seam lead-in plate section adopts high-power laser beam 8-12kw, or low speed of welding parameter 0.5-1.5m/min; After lead-in plate, then use less laser power 8-10kw instead or very fast speed of welding 1-2m/min welds.
Laser penetration weldering two-sides forming is controlled, by butt welded seam, carry out segmentation parameter setting, in welding process, to different weld seam sections, adopt different laser powers or different speed of welding to weld, realize whole even weld penetration and be shaped and control, to guarantee weld seam positive and negative shaping uniformity.
In laser beam welding, often easily there is weld defect in the starting point of weld seam and end point, and for fear of the generation weld defect at weld seam two, the weld seam starting point at banjo fixing butt jointing two ends adds lead-in plate and terminal adds end tab.
Described weld seam two-sides forming adopts LASER or GTAW silk filling multi-pass welding to carry out finishing, obtains smooth, flawless weld seam.
The first square grooves of two Haas alloy-steel plates are integrally welded, and then it is round as a ball to carry out cylindrical shell, and the sheet edge of round as a ball front banjo fixing butt jointing is processed to groove.
The present invention is for the conductive rollers manufacture of laser weld hastealloy alloy cylinder sleeve structure, and dull and stereotyped abutment joint or cylindrical shell longitudinal joint all adopt laser penetration welding, and Haas alloy cylinder shape and weld seam are arranged.Adopt I type joint form, without add filling metal to weld seam, once weld two-sides forming.
Joint assembling is carried out in the butt welding of cylindrical shell longitudinal joint on the fixture of cylindrical shell butt welding.When cylindrical shell is round as a ball, must strictly control ovality and the dimensional accuracy of cylindrical shell, the sheet edge of round as a ball front banjo fixing butt jointing is processed to the groove of certain angle, and the abutment joint after round as a ball just in time forms I type groove.
On fixture, complete after joint assembling, carry out laser beam and the adjusting of seaming position centering, torch height and measure and regulate, laser weld setting parameter etc., then carry out abutment joint laser tack welding.Docking after the distribution of solder joint and the size of solder joint answer guarantee point solid on abutment joint is sewed with enough bonding strengths, and the spacing of laser tack-weld of the present invention is 400mm, and the length of tack-weld is 3mm.
Laser weld is shaped to control and adopts air cooling-copper lining to control back of weld shaping.The air drain that the weld shape that on air cooling-copper lining, machining needs is controlled, processes the passage of several back-protective gas on air cooling-copper lining.Starting needs to lead in advance protective gas to back of weld before welding, drives air; In welding process to weld zone and back of weld remain the high-purity Ar gas that passes into certain pressure.Mobile Ar gas has following effect: prevent that sealing run burning and the root of weld from producing pore, the gas of the certain flow spraying in air cooling-copper lining, has improved the shape that sealing run is shaped.
Beneficial effect of the present invention
Automobile Plate galvanizing technique is not only to conductive rollers appearance Haas alloy cylinder dimensional accuracy, and butt welded seam surface and the very harsh engineering application technology index of inherent quality proposition, do not allow to exist in weld seam incomplete fusion, be mingled with, the detectable defect of Non-Destructive Testing such as cavity, pore, fire check, require weld metal and base metals to there is the ability of identical anti-surrounding medium corrosion simultaneously.Originally conductive rollers manufacture is all import spare part, domesticly also once attempts GTAW (GTAW) bottoming, the method welding of manual electric arc welding (SMAW) capping, but all failures.
The present invention adopts laser penetration solder technology, and it is little that laser weld has beam diameter, and energy density is high, and, without add filling metal to weld seam, realize and once weld two-sides forming; And laser weld is shaped to control and adopts air cooling-copper lining to control back of weld shaping, the gas of the certain flow spraying in air cooling-copper lining, has improved the shape that sealing run is shaped.
The present invention can be used for the welding of the thick Haas alloy of 10mm, realizes one side welding with back formation and controls, and guaranteed the technical indicator of the use of Haas alloy conductive roll.
