针对大拘束度的铸钢构件进行手工电弧焊时易产生裂纹的问题,制定了在焊缝中加入缓应铁带的焊接工艺,从而有效地避免了裂纹的产生,提高了生产效率。
Aiming at the problem that the steel castings with large degree of restraint are easy to crack when they are manufactured by manual arc welding, the welding process of adding slow-acting iron tape to the weld is established, which can effectively avoid the crack and improve the production efficiency.
