焊接薄板容器时,变形是一个很重要的问题。例如,厚度为1～1.5毫米的钢制冰桶,采用气焊也难以保证焊接质量。如果冰桶变形,就不能很好地装在倒冰架内;如果焊缝有气孔,则液密性差,做出的冰就不能吃(有咸味);如果冰桶内表面有较大的焊瘤,做,好的冰就倒不出来。为保证冰桶的焊接质量,可采用水冷气焊法。将冰桶装配和定位焊后,放入水中,焊接时焊接处高于水面约30～40毫米。水温保持在50℃以下。这样,可
When welding sheet containers, the deformation is a very important issue. For example, a steel ice bucket with a thickness of 1 to 1.5 mm can hardly ensure the welding quality by gas welding. If the ice bucket is deformed, it can not fit well inside the ice tray; if the weld has blowholes, the liquid tightness is poor and the ice made can not be eaten (salty); if the inner surface of the ice bucket is larger Welding torch, do, good ice will not pour out. To ensure the quality of the ice bucket welding, water-cooled gas welding method can be used. The ice bucket assembly and positioning welding, into the water, welding welding above the surface of about 30 to 40 mm. The water temperature is kept below 50 ℃. That’s right
