The drawing only specifies the electrode grade – is this a recommendation or a requirement?

As shown in the figure. Is the welding material grade specified in this way recommended for use, or is its use mandatory? If switching to TIG welding, is it necessary for the design team to provide clarification? Is there any standard basis for this?
Once a file is created, it must be executed according to the file’s instructions!
Yes, you need to follow the design documents; if changes are required, then the changes must be designed first
Submit a change order to the design institute to modify the welding method, in order to clarify responsibilities
Why are there always people asking extremely stupid questions? Follow the design documents strictly; if there are any issues, you can say it’s the designer’s fault. If you’ve already decided, then why design at all? When a problem arises, the designer will say that you didn’t follow the design documents. So why go through all this trouble in the end? There are really too many such situations; one always feels that someone else understands something better, or has more experience than oneself. When nothing goes wrong, you’re indeed the best – that’s true. But when problems arise, only if you can provide perfect explanations regarding design, manufacturing, installation, and so on can you be considered great.
There are always people who want to take shortcuts. The regulations exist to help us work safely and improve production efficiency; they’re not meant to harm us. So why do people keep failing to follow the established procedures?
The heat transfer oil pressure pipeline project I was involved in: when the quality inspection agency reviewed the completion drawings, we did exactly as you mentioned. We are asked to ask the design institute to make changes ； Either redraw the drawings.
In the design drawings for welding equipment, the type of welding material is generally not specified. However, many drawings do require the use of a specific welding material. This is because the design of welded structures focuses on structural dimensions and ensuring that mechanical calculations are satisfactory; welding is not the strength of those who design welded structures. If such an issue arises, experiments should be conducted to verify the mechanical properties of the material. In some cases, the drawing creators work in partnership with welding material manufacturers, who then recommend their own materials for use. If this is not the case, there’s no need to pay attention to the welding material specified in the drawings – as long as there is proper process validation, customers generally won’t raise any objections.
