We can see that the welds in some straight welded pipes are very beautiful, and some are very black and obvious. What's the matter? This is mainly due to the difference between adding protective gas to stainless steel pipe welding machine or not. The effect of adding protective gas and not adding protective gas is different.

If protective gas is added to the stainless steel pipe welding machine during pipe welding, the welding line at the weld position is generally bright and smooth, which looks more comfortable. If protective gas is added to the mold during pipe welding, the weld looks scorched. For different materials, the weld is different, and some look like obvious scars, which are not beautiful.

In addition, whether protective gas is added during the pipe welding process of stainless steel pipe welding machine will not only affect the appearance of the weld, but also affect the welding quality of the weld. For the welded pipe with protective gas, the weld quality is relatively stable. If there is no protective gas, the weld position is relatively brittle and it is not easy to carry out secondary processing.

The stainless steel pipe welding machine adds protective gas in the pipe welding process, and the quality of the welded pipe will be significantly improved. It is suggested that for the welded pipe with requirements, it is better to add protective gas and compare the quality first.
