(i) Consider the welding methods used mainly in fabricating the members and joints of architectural structures.
ex) Large-heat-input welding: SAW, FCAW, ESW | (i) Fix current and voltage.
(ii) Control the amount of welding heat input by varying the welding speed. | (i) Depending on the chemical composition of welding materials, affected are the deposited metal by large-heat-input welding and the embrittlement of HAZ part.
(ii) Consider the application to welding rod products. | (i) In general, the thicker the base materials get, cracks may be created due to the increase in the degree of constraints for welded areas and the contraction stress.
(ii) Apply to 35 mm, 40 mm, 80 mm, and 100 mm rear plates. | (i) AWS D 1.1. Apply standard welding details to V/dam welding (35 mm, 40 mm) and X-type groove welding (80 mm, 100 mm) examined in advance in the standard specifications of architectural construction.
(ii) The welding posture is 1 G. |
