Is it hard to read welding blueprints?
Unfortunately, a large number of welders have a hard time reading blueprints correctly. The ones that do take classes either do not get trained on blueprints or decide not to pay attention to the written material. The result is that only a few welders know how to read blueprints accurately or use them in their work.
How do you read a weld drawing?
The weld symbol distinguishes between the two sides of a joint by using the arrow and the spaces above and below the reference line. The side of the joint to which the arrow points is known (rather prosaically) as the arrow side, and its weld is made according to the instructions given below the reference line.
How do you read blueprints easily?
4 Tips for Reading Blueprints
- Begin with the title block. The title block is the first piece of information you’ll see in construction site plans.
- Study the plan legend.
- Find the blueprint’s scale and orientation.
- Look for notes from the architect.
Do you think it is a bad weld or good weld?
Characteristics of a Good Weld The sign of a quality and secure weld is that you will not see the weld at all. If there is any visible evidence of a weld, it will be in the form of a bead that has no holes or cracks and is uniform overall. A high-quality weld is made using high-quality materials.
What are the welding codes?
List of welding codes
- American Society of Mechanical Engineers (ASME) Codes.
- American Welding Society (AWS) Standards.
- American Petroleum Institute (API) Standards.
- Australian / New Zealand (AS/NZS) Standards.
- Canadian Standards Association (CSA) Standards.
- British Standards (BS)
How do you read welding electrode codes?
2. What do AWS stick electrode classifications mean?
- The letter “E” indicates an electrode.
- The first two digits represent the resulting weld’s minimum tensile strength, measured in pounds per square inch (psi).
- The third digit represents the welding position(s) for which the electrode can be used.
What is a break line on a blueprint?
Break Line They are used to remove, or ‘break out” part of a drawing for clarity, and also to shorten objects which have the same shape throughout their length and may be too long to place on the drawing. Short and long break lines are used for flat surfaces.
How do you read a blueprint?
The first number represents the actual size of the part and the second number represents the print. In other words, 1:2 means the the print is double the actual size. Whereas 3:1 indicates the actual size is three times what is shown on the print.
Does grinding a weld weaken it?
If you do grind a perfect weld, yes it will make it weaker. If you just want to smooth it a little to make it look nicer, it will weaken it a little bit but should still have structural integrity. Grinding a weld doesn’t always weaken the weld, but may.
