摘要： Provided are: an arc welding method that suppresses occurrences of blow holes in initial parts and final parts in a Zn plated steel sheet and reduces the occupancy ratio for blow holes in the welded part as a whole; and a welded joint. An arc welding method for a Zn plated steel sheet sets the gap between plates to 0.2 - 1.5 mm and includes a first step for moving a welding means from a welding initiation point at a first welding speed and performing welding by applying a first welding heat input, a second step following the first step for moving the welding means at a second welding speed and performing welding by applying a second welding heat input, and a third step following the second step for stopping the movement of the welding means and performing welding for 0.1 - 2 seconds at that stopped position. The first step includes welding performed on a welding unit under conditions wherein the first welding speed is less than the second welding speed and the first welding input heat exceeds the second welding input heat. In the third step, welding is performed at a welding current and a welding voltage lower than those in the second step.

摘要： The present invention provides a steel sheet hot-dip-coated with a Zn-Al-Mg-based system for welded structural members, which can be used as a steel material suitable for an arc-welded structural member and which is significantly improved in all of burring workability, molten metal embrittlement cracking resistance, and corrosion resistance at welded parts. This steel sheet hot-dip-coated with a Zn-Al-Mg-based system for welded structural members has a Zn-Al-Mg-based hot-dip coating layer on the surface of a base steel sheet, wherein the base steel sheet has a specified chemical composition and has such a metallic structure that Ti-containing precipitates having an average particle diameter of 20 nm or smaller are dispersed in a matrix composed of a ferrite phase, and the relationship between the contents of steel components and the thickness (t) (mm) in the base steel material is such a relationship that a molten metal embrittlement cracking sensitivity index (H3 value) represented by formula (3) is 2.90 or less. H3 value = C/0.2+Si/5.0+Mn/1.3+Cr/1.0+Mo/1.2+0.4t-0.7(Cr+Mo)1/2 (3)
