The welding deformation not only have bad effect on the good appearance, but also can result in all kinds of weld cracks.
焊接变形不但影响美观,还可能会引发各种焊接裂纹。
After being heated the alloy's plasticity becomes bad, easy brittleness, not to be easy to weld.
被加热后,合金的塑性变差,易脆性大,不容易焊接。
The results indicate that the brittle intermetallic compound in weld is the main reason why the weldability of the plate is bad, which leads to cracks under the effect of welding stress.
通过分析TA2和Q 235b的焊接性,论述了钛与钢熔焊焊缝脆裂的机理,指出钛钢复合板焊接性能差的主要原因在于焊缝中产生了脆性的金属间化合物,从而导致焊缝在焊接应力的作用下发生开裂。
