02-UNDERSTANDING WELDING ARROW

A quick recap. Welding arrow at a skeleton level consists of three components;

• Reference Line (Mandatory part // Always is a straight horizontal line)
• Arrow line (Mandatory part // Never drawn Horizontally)
• Tail (Non mandatory part // Used to specify general information)

You can connect multiple arrows to a single reference line & Tail is connected to the reference line at the opposite end of the arrow. (For details please refer to my 1st post ).

Now, lets consider the reference line and understand how it is bifurcated  into other side & the arrow side.

So, we know that reference line is always drawn horizontally. Top side of reference line represents the other side; Bottom side of the reference line represents the arrow side.

Lets, further understand the concept of other side & arrow side by considering most commonly used welding joints;

T Joint 

Lap  Joint 

Butt Joint
