Title:
WELDING METHOD OF VIBRATION DAMPING SECTION MEMBER
Document Type and Number:
Japanese Patent JP3835864
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a welding method of a vibration damping section member capable of securing good weld penetration by way of giving no adverse effect to weldability at the welding, without lowering its damping property so much, even in case of this damping section stuck with a damping resin material on a thin aluminum plate of less than 2mm as well as enabling it to prevent any possible deterioration of bead of bead form due to an excessive weld heat input, thereby making good welding operability securable.
SOLUTION: In time of welding a vibration damping section member 1 stuck with a damping resin material on an least one side of an aluminum or aluminum alloy plate 2, it is welded at a straight polarity ration ranging from 5 to 20% by an alternating current pulse MIG welding process which supplies a reverse polarity arc and a straight polarity arc alternately from the backside of a surface where damping resin material 3 of the aluminum or aluminum alloy plate 2 is stuck fast. In this connection, in this damping resin material 3, each hole 3a is formed in respective positions where plural pieces of first line rows 4 extending in the first direction and plural pieces of second line rows 5 extending in the second direction being intersected with the first direction, within the surface.
