Abstract
The invention discloses a welding method, and particularly discloses a single-side welding and double-side molding method for carbon-dioxide arc welding. The single-side welding and double-side molding method for carbon-dioxide arc welding is characterized by comprising the following steps that a ceramic liner is pasted to the back face of the groove side of a barrel, nitrogen is led into the position where the back face of the groove side of the barrel and the ceramic liner make contact, and the head end of a welding gun is fixed to an extension arm of an automatic submerged arc welding machine so as to weld the groove side of the barrel automatically. The single-side welding and double-side molding method for carbon-dioxide arc welding has the beneficial effects that the ceramic liner has the characteristic of resisting high temperature so as to be used for supporting weld metal on the back face of the groove side of the barrel; the weld metal can be effectively protected against oxidation by leading the nitrogen to the back face of the groove side of the barrel, so that the appearance quality of welding seams is improved; besides, the welding seams are not prone to deformation as being cooled through the nitrogen. Due to the fact that the welding gun is bound to the automatic submerged arc welding machine, welding is more stable, the molding and quality of the welding seams in the front side are ensured, and the welding deformation possibility is effectively reduced.
Description
Technical field
The present invention relates to a kind of welding method, particularly relate to a kind of method of carbon-dioxide arc welding single-side welding double-side forming.
Background technology
Current, when making cryogenic liquid semitrailer inner pressurd vessel with the steel plate of 4-5 millimeter, with the general welding method series of problems such as have the large and welding efficiency of distortion low, if employing Plasma Welding, although be out of shape little, efficiency is high, but welding equipment investment is huge, and medium-sized and small enterprises are difficult to bear investment expense.
Therefore, invent a kind of welding effect good, be out of shape little, be easy to control and the method for the low carbon-dioxide arc welding single-side welding double-side forming of cost of investment becomes those skilled in the art's problem demanding prompt solution.
summary of the invention
The present invention proposes a kind of method of carbon-dioxide arc welding single-side welding double-side forming, and the method distortion of this carbon-dioxide arc welding single-side welding double-side forming is little, and welding effect is good and cost of investment is low.
The present invention solves the problems of the technologies described above adopted technical scheme as described by below:
A method for carbon-dioxide arc welding single-side welding double-side forming, is characterized in that: comprise the steps:
Paste ceramic substrate at the back side of the groove side of cylindrical shell, and lead to nitrogen in the contact position of the back side that cut is surveyed and ceramic substrate, arc welding gun head is fixed on the extension arm of Lincoln weld welding machine, carries out automatic welding to groove side.
The invention has the beneficial effects as follows: have employed ceramic substrate and there is resistant to elevated temperatures characteristic; can be used for setting off the weld metal at the back side; the back side leads to nitrogen can protect weld metal effectively; make it not oxidized; thus improve the presentation quality of weld seam; and cool with nitrogen butt welded seam, weld seam is not easy distortion.Welding gun is bundled on the welding machine of Lincoln weld, not only makes welding more stable, guarantees the shaping of fillet in normal shear and quality, also effectively improves welding deformation.
