Metal powder addition in submerged arc welds
Study on the feasibility of metal powder addition in submerged arc welding (SAW) of steel was carried out and its effect on the deposition rate and mechanical properties of welds was evaluated. The principal objective of the work was to increase the deposition rate of SAW process without increasing...
