Diagram Information and Instructions

Foreword

ILLUSTRATION EXAMPLE
- Symbols and number of points indicate the welding method and the number of welding points. Text in brackets indicates the direction for removal of welded parts, and numbers indicate the number of plates to be drilled in panels of welded parts to be removed.
- An enclosure by a broken line indicates work from the opposite side (rear side).







REMOVAL DIRECTION

Division is made into the four groups of inside, outside, top, and bottom, and these directions are defined as shown in the following figure.







NUMBER OF PANELS TO BE DRILLED

Depending on the number of panels, drilling is done through one panel or two panels, and this number is listed together with the removal direction.

1. Drilling through one plate







2. Drilling through two plates







HOLE DRILLING FOR PLUG WELDING

1. Drilling of holes for plug welding in service parts







2. Drilling of holes for plug welding in service parts, matching the holes on the vehicle side







MEANING OF SYMBOLS
















CAUTION

Since there is a possibility that the required strength will not be obtained, an inverter welder must be used for spot-welding at locations where high-strength steel is used.

NOTE

On 980MPa class High-strength tensile steel

It is recommended to perform the weldings using 980Mpa class high-strength steel under the following conditions.
- It is recommended to perform spot welding according to board thickness and number of overlapping sheets under the following conditions ([a] - [f])
- When conditions can't be met, it is recommended to perform the plug welding following [g] or [h].
