The paper describes TIG, SMAW and SAW as basic welding processes used for pipe / tube welding in boiler production. Type of base metals, joint preparing ,welding parameters and shielding gases are the most important variables which are defined in WPS. For mechanized welding processes the most important is mechanical preparation of the edges-joint. Welders and operators education and training, workshop control before, during and after welding are integral parts of the quality assurance of process. |
