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

01-UNDERSTANDING WELDING ARROW

I am a stickler for details (A typical Virgo Characteristic); If you find this post too basic or too detailed, you can skip the post & watch the video; What ever suits you.

This is my way of sharing knowledge/ Understanding to benefit a few; Basically, intention is to share whatever i learn; So posts & topics are not structured...

At a skeleton level, welding arrow consists of three components;

     1. Reference line 

     2. Arrow

     3. Tail

Now, When it comes to reference line, you need to remember two things.

• Reference line is always a straight line
• Reference line is always Horizontal

Second component i.e.Arrow, consists of two components;

• Arrow head & Stem;

• Arrow typically points towards the weld joint under consideration; Stem connects the arrow head with the reference line; 

When it comes to arrow, remember that it is never horizontal. 

"Reference line is always Horizontal; Arrow line is never Horizontal"

Arrow can be connected to either end of the reference line. Arrow can be in any orientation; Even Multiple arrows can be connected to  single end of the reference line. 

Third component i.e. Tail, is not a mandatory part of the Welding symbol. It is usually represented by greater than (>) or less than (<) symbol;

Tail is connected to the reference line (i.e. at the opposite end of the arrow head);

Tail is used to  indicate extra or general information which cannot be specified on other part of the arrow;
