Before practicing a V-groove weld in the overhead position (4G),you should a) change to constant voltage DC b) build a practice pad with stringer beads c) increase the amperage to the top of the correct range d) change to E6010 electrodes

Answer 1

4. If a groove for a weld goes through the entire base metal thickness, it makes a(n) __a) complete joint penetration (CJP) weldb) subsurface joint penetration (SJP) weldc) partial joint penetration (PJP) weldd) axial joint penetration (AJP) weldThe correct answer is a) complete joint penetration (CJP) weld.Explanation: When a groove for a weld goes through the entire base metal thickness, it is considered a complete joint penetration (CJP) weld. This means that the weld metal has penetrated through the entire thickness of the base metal, resulting in a strong and stable weld joint.5. Before practicing a V-groove weld in the overhead position (4G) you should __a) change to constant voltage DCb) build a practice pad with stringer beadsc) increase the amperage to the top of the correct ranged) change to

electrodesThe correct answer is b) build a practice pad with stringer beads.Explanation: Before practicing a V-groove weld in the overhead position (4G), it is recommended to build a practice pad with stringer beads. This allows the welder to practice and develop their skills in a controlled environment before applying the weld on the actual joint. Building a practice pad with stringer beads helps the welder to understand the proper technique and achieve a high-quality weld.
