What problems should be paid attention to when welding elbow?

Elbow welding is a technical work. The principle of elbow welding is to use a heated iron to heat and melt the solid solder wire directly, and then use flux to ensure that it can smoothly flow into the metal to be welded. When it is thoroughly cooled, it can form a reliable and strong welding point.

If the bent pipe welding, if tin lead alloy welding surface is mainly copper, so it is necessary to ensure that the solder welding appearance on wet, wet occur constantly, to ensure the solder to the direction of the copper is dispersed, and can effectively ensure the effect of adhesive layer, promote both sides can be beneficial to combine.
