Describe the metric welding symbol practices such as those used in the British Standard.

Question

What will be an ideal response?

Answer 1

Metric welding symbol practices such as those used in the British Standard include a dashed line next to the solid reference line for certain applications. Weld symbols drawn on the solid reference line relate to welds on the arrow side of the item being welded. Use caution when comparing this method to the AWS standard, because there are differences that can cause confusion. Weld symbols on the dashed line relate to a weld on the other side of the item. If the dashed line is above the solid line, then the symbol for the arrow side weld is drawn below the solid reference line and the symbol for the other side weld is above the dashed line. The dashed line is omitted if the welds are symmetrical on both sides of the item being welded.
