Laser Cutting 12000W
Too much weld reinforcement reduces fatigue strength, whereas too little leads to understrength and defects.
t of Flange≦40mm Tolerance 0≦⊿h≦7mm
h(height)＝ t/4 + ⊿h (t=9mm)

Root Gap
Laser Cutting 12000W
Welding Temperature Control
If the root gap is too wide, the molten metal falls through the bottom. If it's too narrow, the weld won't reach the bottom, causing a lack of strength.
Welding Temperature Control
Welding Temperature Control
Welding Temperature Control
Maintaining the inter-pass temperature below 250°C suppresses grain coarsening, which prevents the deterioration of toughness in both the weld metal and the heat-affected zone (HAZ)
Misalignment
Welding Temperature Control
Misalignment
Inspect every joint of the columns and panels for misalignment.
UT TEST
Welding Temperature Control
