Abstract
A welding device and a welding method for butt welding two pipes to be welded are provided. The welding device comprises a welding device body, having an electrode unit with a welding electrode and a fixing clamp for holding the pipes to be welded; and electrode position indicating means for indicating a position of the welding electrode with respect to the pipes to be welded. The electrode position indicating means is capable of irradiating an indicating light to the pipes to be welded at the position corresponding to the welding electrode. Therefore, the positions of the butt edge surfaces of the pipes and the welding electrode can be easily and correctly consistent so as to perform a good welding.
