QG—E级低合金高强铸钢的焊修工艺
REPAIR WELDING PROCEDURE FOR QG-E CLASS HSLA CAST STEEL
【摘要】 通过最高硬度试验和斜Y形坡口焊接裂纹试验,研究了预热对QG-E级低合金高强铸钢焊接性的影响,并制定了相应的焊修工艺.实际应用表明,该工艺满足了MT—2型大容量缓冲器箱体技术要求.
【Abstract】 Effect of preheating on weldability of QG-E class HSLA caststeel are studied by hardness test and Y-groove crack test. From these process, the repair welding procedure is determined. Welding practice indicates that the procedure used fulfills technical requirements of large volume MT -2 compression bumper.
