Briefly describe the tack weld process.
What will be an ideal response?
To tack weld,proceed as follows:
| 1. | Hold the damaged area in alignment with clamps or aluminum body tape. |
| 2. | Using a tacking welding tip,fuse the two sides to form a thin hinge weld along the root of the crack.This is especially useful for long cracks because it allows for easy adjustment and alignment of the edges. |
| 3. | Start tacking by drawing the point of the welding tip along the joint. Press the tip in firmly, making sure to contact both sides of the crack.Draw the tip smoothly and evenly along the line of the crack. No welding rod is used when tacking. |
| 4. | The point of the tip will fuse both sides in a thin line at the root of the crack.The fused parts will hold the sides in alignment. Then you can fuse the entire length of the crack. |
