对实际生产中等离子加机械钨极氩弧焊(P+T)焊接方法出现的裂纹进行了分析以及模拟实验,实验结果表明焊接裂纹是由于焊接过程中引入的外来低熔点金属引起。
The actual production of plasma plus mechanical TIG welding (P + T) welding crack analysis and simulation results show that the welding crack is due to the introduction of foreign low melting point metal during welding caused.
