A C[O.sub.2] laser-MAG hybrid welding process for DH36, a higher-grade shipbuilding steel with a low temperature toughness requirement, has been reported by researchers at TWI Ltd., Cambridge, England. In laser-arc hybrid welding, a welding arc and a laser beam converge in a single molten pool.

The process thus allows some of the disadvantages of the separate processes to be overcome, such as the low tolerance to joint fit-up of the laser, and the limited penetration of the arc welding process. For these reasons, laser-arc hybrid welding is already applied in some industries, ...
