Welding Methods for Two Elbows of Any Angle:

① Angle Depends on "Eyesight"

First, position the two elbows on the muddy ground at the desired angle (e.g., 45° or 60°) and temporarily support them with wooden sticks. A veteran welder's secret is: "If the angle is off, look at the shadow; sunlight will immediately reveal it!"

② Spot Welding to "Fix the Joint"

Use an electric welder to spot weld three points at the elbow joint to form a triangle. The motto is: "Three points define the joint. Shake it after welding. If it doesn't move, weld it back in place."

③ Welding Like Embroidery

When welding, move the electrode in a constant Z-shaped pattern to ensure the weld fills the gap evenly. When working in muddy ground, be especially careful: "After welding, knock off the slag shell. If the slag is not completely removed, the weld will leak!"
