Laser-MAG复合焊接热源相对位置焊缝成型 laser-MAG hybrid welding relative position of heat source weld forming

摘要

Laser-MAG复合焊接具有焊接速度快、自动化程度高、焊接热变形小等优点, 是船舶焊接技术发展的重要方向。采用 Laser-MAG复合焊接方式, 通过改变两种热源的相对位置, 对10 mm厚船用高强钢EH36进行了堆焊试验。研究了激光引导电弧(L-A)和电弧引导激光(A-L)两种行走方式以及激光与电弧之间夹角大小对焊缝成型的影响。结果表明, Laser-MAG复合焊接中, A-L焊接方式相较L-A焊接方式对焊缝表面成型更有利, 成形更均匀, 但飞溅量更大, 其焊缝熔宽较小, 熔深较大; 无论是L-A还是A-L焊接方式下, 焊枪与竖直方向夹角越大, 焊缝成型越不稳定、飞溅量越大, 但焊缝熔深几乎不受其影响。

Abstract

Laser-MAG hybrid welding has the advantages of fast welding speed, high degree of automation, and small thermal deformation, which is an important direction for the ship welding technology development. 10 mm thick marine high-strength steel EH36 was surfacing test that using the Laser-MAG hybrid welding method by changing the relative position of the two heat sources. The effects of laser guided arc(L-A)and arc-guided laser(A-L)two walking modes and the angle between laser and arc on the weld formation were studied. The results show that compared with L-A welding, the A-L welding method is more favorable for forming the surface of the weld in Laser-MAG hybrid welding, the forming is more uniform, but the amount of spatter is larger, the weld width is smaller and the penetration depth is larger. Regardless of the L-A or A-L welding mode, welding torch and vertically angle is greater, the more unstable weld formation, the greater the amount of spatter, but the weld penetration is hardly affected.
