摘要： Provided is a welding method which can improve the joint strength while enabling simplification of the welding processing. It is a welding method for joining a plurality of members to one another by fusion welding, comprising the steps of: abutting a joint area of another member to a member having a substantially plate-type part as a joint area; and applying welding processing by using a prescribed welding device from a face of the substantially plate-type part opposite to the one onto which another member is abutted for melting the substantially plate-type part to join each member to one another.

摘要： Hot cracking in laser welds produced in metal workpieces, especially aluminum or magnesium sheet alloys, is avoided by suitably combining the beams of two different lasers, for example a CO2 laser and a YAG laser, into a compound beam that is moved along a weld path in the surface of the workpiece. The power level of at least one of the lasers is cyclically varied so that weld nugget segments of different alternating, hot crack free, configurations are produced in a linear weld.
