Thank you for your supported.
We send the picture to your consider.
In the 2nd picture, We have problem point to high cove. Because, it has less space in the welding.
In the 3rd picture, it’s good product. I had welded by employee have high skills.
In the 4th picture, it’s NG product. Because material can not filler into inside but It’s over only outside.
We known, the problem is skill of employee. But we can not train employee to high skill just one day.
Thus, We thought that, if we change use the brazing rod smaller. We can solve this problem.
Therefore, We will try to welding by brazing smaller size.
