WELDING APPARATUS HAVING A REINFORCING CONVEX PART WHICH IS FORMED IN AN EXTENSION BAR OF A POWER TRANSMISSION MEMBER IN A WELDING MEMBER LIFTING UNIT

摘要

PURPOSE: A welding apparatus is provided to prevent a welded part from becoming eccentric by controlling the descending height of a welding member according to the thickness of a material to be welded.;CONSTITUTION: A welding apparatus comprises a main body(120), a material thickness measuring unit(140), and welding members(160). The main body includes a platform(122) in which a material(S) is fixed. The material thickness measuring unit measures the thickness of the material fixed to the platform. The welding members are installed in the main body and cooperate with each other to weld the material. The welding members are raised and lowered by a lifting unit(124) according to the measured thickness of the material. The lifting unit includes a power transmission member having an extension bar in which a convex part is formed to increase strength against the pressing force of the welding members.;COPYRIGHT KIPO 2012
