在金属焊接加工过程中,为了保持表面光滑美观,在焊接时应该遵循以下焊接守则:
In the process of metal welding, in order to keep the surface smooth and beautiful, the following rules should be followed in welding:
1、在焊接铝等导热性好的金属时,为了减少焊接变形,应采用比母材导热速度快的焊接速度。
1, in the welding of aluminum and other good thermal conductivity of metal, in order to reduce the welding deformation, should be used than the base metal heat conduction speed welding speed.
2、焊接有热裂倾向的合金不能采用高速度焊接。
2, welding hot cracking tendency of the alloy can not use high speed welding.
3、焊接熔池的尺寸会直接受焊接速度的影响,当在非平焊位置焊接时只能是较小的熔池,应适当提高焊接速度。

3, the weld pool size will be directly affected by the welding speed, when only in non flat position welding pool is small, should be appropriate to increase the welding speed.

4、 在金属焊接加工过程中遵循一定的焊接守则,可以保证产品的焊接质量和美观度。
4, in the process of metal welding in accordance with certain rules of welding, can ensure the quality of the product quality and beauty.
5、由于各种焊接方式都有一定的差异,所以焊接时要牢记这些守则,可以防止产生焊接缺陷的问题。焊接从母材和焊条熔化到熔池的形成、停留、结晶,其过程发生了许多的冶金化学反应。
5, due to a variety of welding methods have some differences, so to keep in mind the rules of welding, can prevent the problem of welding defects. The process of welding from the base metal and the welding rod to the formation, retention and crystallization of the molten pool has undergone many metallurgical chemical reactions.
