Abstract
The utility model provides a welding set convenient to carbon quenched and tempered steel weld quality in control connects gradually welder, infrared focus banks and mechanical rolling machine and constitutes at same walking platform, and it can comprehensively improve the weld crack, connect mechanical properties and welding deformation, and does not influence production efficiency. The utility model discloses can make weld quality's control go on along with welding, easy operation, production efficiency height, with low costs, the practicality is strong.
Description
Technical field
The utility model belongs to welding technology field, relates to a kind of welder.
Background technology
Carbon in middle carbon quenched and tempered steel is higher with other alloying element content, can obtain higher strength character, be applied to important engineering component and machine components more, as aircraft primary structure member, rocket envelope, armour steel, ocean platform high pressure line etc. by modifier treatment.But middle carbon quenched and tempered steel carbon containing is high, tendency of hardenability is large, and easily produce cold crack when welding under quality adjustment condition, weldability is poor, heat affected area easily embrittlement occurs and affects impact flexibility.In improvement, the conventional means of carbon quenched and tempered steel weldability and control heat affected zone embrittlement is the timely after heat of preheating and postwelding.No matter preheating and after heat are all a set of processes independent of welding, not only worsen welder's working condition, affect production efficiency, and affect by welded, for the weldment being difficult to overall preheating or after-baking, local heat may bring additional constraint stress, and the regulating effect of welding cold cracking is limited.Cold crack and welding deformation are a pair relative paradox, and control welding cold cracking wishes less constraint (restraint) degree, but may cause larger welding deformation.
Summary of the invention
The purpose of this utility model is to provide a kind of welder being convenient to carbon quenched and tempered steel weldquality in control, and it can comprehensively improve weld crack, joint mechanical performance and welding deformation, and does not affect production efficiency.The utility model additionally provides a kind of cal rolling device for controlling welding deformation.
For achieving the above object, the utility model adopts following technical proposals:
Be convenient to a welder for carbon quenched and tempered steel weldquality in controlling, comprise welding gun, infrared focus lamp group and cal rolling device, it is characterized in that: at same travelling platform, connect welding gun, infrared focus lamp group and cal rolling device successively.
Described infrared focus lamp group is made up of two or the infrared focus lamp of multiple stage.
Described infrared focus lamp is that heater element produces infrared ray and carries out irradiating the device of heating through reflect focalization to workpiece.
Cal rolling device comprises: handle, rail plate, base, support, rolling wheel, spring and unit head, handle active link rail plate, and the bottom of rail plate connects base, subbase connection support, support fixed-link rolling wheel, on support, cover has spring, and rail plate connects unit head.
The utility model can make the control of weldquality carry out with weldering, simple to operate, production efficiency is high, and cost is low, practical.Realize the Comprehensive Control of weld defect, joint mechanical performance and welding deformation, the quality that postwelding joint is good can be ensured.

In figure 1---welding gun; 2---workpiece; 3---travelling platform; 4---infrared focus lamp group; 5---infrared focusing etc.; 6---cal rolling device 7---handle 8---rail plate 9---base 10---support 11---rolling wheel 12---spring 13---unit heads.
Detailed description of the invention
For the ease of understanding, illustrate the utility model in detail further below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of welder being convenient to carbon quenched and tempered steel weldquality in control, comprise welding gun 1, infrared focus lamp group 4 and cal rolling device 6, at same travelling platform 3, connect welding gun 1, infrared focus lamp group 4 and cal rolling device 6 successively, infrared focus lamp group 4 and cal rolling device 6 are with welding gun 1 synchronous walking.
As shown in Figure 1, infrared focus lamp group 4 is made up of the infrared focus lamp 5 of multiple stage.
As shown in Figure 2, cal rolling device 6 is made up of handle 7, rail plate 8, base 9, support 10, rolling wheel 11, spring 12 and unit head 13, handle 7 active link rail plate 8, the bottom of rail plate 8 connects base 9, base 9 connection bracket 10, support 10 fixed-link rolling wheel 11, on support 10, cover has spring 12, and rail plate 8 connects unit head 13.
During use, regulate infrared focus lamp group 4 and welding gun 1, the distance of infrared focus lamp group 4 and face of weld, postwelding, control rethermalization time and the temperature of infrared focus lamp group 4 butt welded seam, make quench zone in the left and right temperature slow cooling of Ms point, reduce hardened structure--the generation of high carbon martensite, thus reduce cold crack, raising joint impact flexibility.
Regulate the distance of mechanical rolling device 6 and welding gun 1, regulating handle 7, control the distance of rolling wheel 11 minimum point and face of weld, thus control rolling wheel 11 to the amount of rolling of hot weld seam.When weld seam is still in hot plastic state, cal rolling device 6 butt welded seam rolls, and makes weld metal effectively extend and control welding deformation.
