前言目前,薄板材料的电弧焊接(如氩弧焊)尚存在下列几个明显的弱点: 1、对规范参数变化的影响非常敏感。如电流稍大或焊接速度较慢时极易烧穿,反之则焊不透。 2、对装配要求很严。如间隙稍大就易烧穿。 3、对胎模具的要求很高。焊环缝时的胀紧程度或纵缝的压紧程度不同时,松的地方极易烧穿,紧的地方则焊不透。鉴于上述诸问题的存在,阻碍了自动 Foreword At present, there are still some obvious weaknesses in the arc welding of sheet metal materials (such as TIG welding): 1. The impact on the change of gauge parameters is very sensitive. If the current is slightly larger or welding speed is very easy to burn through, otherwise the opaque. 2, very strict assembly requirements. If the gap is slightly larger easy to burn through. 3, the requirements of the tire mold is high. When the welding ring seam expansion or longitudinal compression of the degree of compression is not the same time, loose areas easily burn through, the tight place is impermeable. In view of the above problems, hindered automatically
