Welding: What should be paid attention to? Please give me some advice

Our company, which manufactures tower equipment, does not have protective panels for welding ladders; we now want to weld them on-site. Is that possible? The material is a Class 2 pressure vessel made of 16MNR. Welding: What should be paid attention to? I would appreciate your advice. Thank you! !
Ladder platform guard? ? ? ? I’m not sure what the original poster is trying to say~~~ Be careful: if this tower has already been heat-treated, welding on it cannot be done casually!
It should be possible to weld it. I have seen the supports for welding platforms and steel platforms at methanol pressurization tower sites. During the welding process, it is necessary to comply with the manufacturer’s requirements regarding hot work, obtain the relevant permits, and provide pre-job training for the welders.
If welding is really necessary, you can heat it up with an oxy-acetylene torch after welding.
It is completely fine if the equipment is not subjected to heat treatment; it’s just not convenient to do so in the manufacturing facility. Relevant procedures need to be followed, and appropriate tests must be conducted after welding. If it has been heat-treated, that’s a bit of a problem: lol. In theory, welding should not be done again after welding; instead, heat treatment is required (either overall in a furnace or locally).
I. As long as no welding is carried out on the device itself, it’s fine no matter what! II. How to perform welding on the equipment itself? Please have the manufacturer complete the application first before moving on to the next step!
Welding work on the equipment itself (a Class 2 pressure vessel of type 16MNR) is not permitted; on-site welding is not allowed at present! Go through the relevant procedures! !
What procedures need to be followed? Are there any regulations regarding welding plates onto pressure vessels?
