low heat input

Weld whose heat resource is the laser, also owns the advantage such as low heat input and small heat deform.

以激光为热源的焊接同样也可以得到低热输入、变形量极少的效果。

If welding procedure tests have been performed at both a high and a low heat input level, then all intermediate heat inputs are also qualified.

如果焊接工艺试验在高热输入值和低热输入值下进行，那么，中间的热输入也应合格。

A new large heat input welding high strength low alloy steel with low susceptivity to weld cold cracking was developed and the cold strain aging behavior was investigated.

研制了一种低焊接裂纹敏感性高能量输入焊接用低合金高强钢，并研究了其冷应变时效行为。
