What is the impact of welding to the end without drying the electrode?
Thread Content
I have never done welding before, but the welding specifications as well as the manufacturer’s instructions for the electrodes state that the electrodes need to be dried before use. But from what I’ve observed, aside from large state-owned enterprises that properly comply with these regulations, ordinary private enterprises don’t bother with them at all. Not to mention drying it, even if it gets wet, as long as it can be welded, just weld directly on it. I would like to ask welders who have experience in welding: what impact does it really have on the weld seam whether the area is fully heated during welding? Does it make welding more difficult if the area gets damp, or does it make no difference? If the welding process is the same in all cases, will there still be quality issues such as pores in the weld seam after welding?
The extent of the impact depends on factors such as the material and manufacturing process; the simplest issue is porosity, while more severe problems include cracks and delayed cracks.

There is a **discount for strength**; weld points become unreliable over time, and the appearance is not attractive either. There are internal quality issues, such as flaw detection problems, so it won’t pass.
I was thinking of asking welders, but it’s probably impossible – those who can access this forum are likely just theorists;P
Sure, it needs to be dried. Whenever welding is performed on pressure vessels, the welding electrodes must be dried as well. This is a standard practice even in private enterprises, with no exceptions
It’s not a big problem to use it on structural components without drying, but for container inspection, there will definitely be many pores. Also, welders won’t do it either – the number of rework pieces is tied to their bonuses; in our company, welders definitely won’t be given welding rods if the parts aren’t dried
You’re looking at it from a one-sided perspective. . . If the welding rod is not dried, the most direct consequence is an increase in pores. . Big! So, whether to bake or not is not determined by the nature of your business; in most cases, it’s the welders who choose to cause trouble by not baking it. . The time needed to dry the electrodes – he might as well play around too: lol Why not?
This is the pipeline welding site; the boss has taken out the wet electrodes and is drying them! The pipes are operated under slightly positive pressure; perhaps for this reason the owner didn’t even bother to prepare a dryer. The welding rods were taken straight from their packaging boxes and used as-is, and when they got wet they were simply dried in the sun. Even after the project was completed, there were hardly any pores. The world is so vast that there are many things not mentioned in standard manuals, and I want to explore the reasons behind them.

Have you been to construction sites before? Driving under the influence doesn’t necessarily lead to an accident, but it’s the same principle here. Besides, we’re also part of a private enterprise
Not drying the electrodes has little impact on the welding quality; however, it does affect the structure of the weld. Things like the purity level mentioned earlier are something that these welders don’t pay attention to. If you ask whether welding with wet electrodes has any effect, it’s similar to asking whether washing vegetables before cooking makes a difference
