Air Temperatures and Welding

Got a thermometer, Guvnor? Go and measure it. <Cough>

this must be a weirdo site. Or a site where people want answers to questions but yet others with nothing better to do play games.

GA Pete,

""What is the temperature under a welders full face hood."

Well, That depends on many factors, such as:

is it in the Valley of death in mid August?

Is it in the repair bay at the Antarctic observatory?

Is the welder breathing heavily, overweight, and sweaty?

Is the welder calm cool and collected?

Flip screen or flip up hood?

etc etc etc.

What is the purpose of your question?

the purpose of the question smartass, is to find out how safe it it to wear plastic rings in one's face.

Well, why didn't you say that? Why are you making people pull the question out of you? The more specific you can be, the higher the likelihood that you'll get a good answer. Attacking other posters because they can't read your mind isn't going to help anyone.

thanks for the lecture guest. You were a lot of help too. Just like the other clowns with nothing better to do. It was a simple question that i thought somebody would take seriously. I guess i will have to try and find an answer elsewhere since nobody is able to answer other than some stupid comment.

I am amazed at your audacity and defensiveness/aggression, and your lack of ability to understand the significance of the questions that have been asked back to you.

Can you not see understand the difference it would make even between these two hypothetical situations?!?!?!

• Major weld repairs inside a 48" steam drum (confined space) with a 175 deg constant preheat.
• Welding mobile equipment outside in the dead of winter in northern Canada.

Go take your frustrations/ignorance elsewhere!!

No need to get Hasty now. Its hard to answer such a question without asking many more questions about potential variables. I'm unsure what you mean by plastic rings in the face, You speaking of plastic piercings?

In my welding experience there is no amount of heat buildup inside the mask to be of concern. If its hot enough to soften/melt plastic in your face, its definitely too hot to safely work. Wear a quality mask if welding seriously and your face will be fine. I worked with a guy who would smoke cigarettes in his mask with it closed up... not sure how he could do it but he did.

In general, well thought out, clear, questions get good answerers.

Let me use my common sense

a) A welder wears a mask, which is in contact (at least at several places) with his skin, of face, which is supposed to be the relatively sensitive one.

b) The normally as I remember > 50⁰C is hot for skin contact and > 60^oC or so is too hot.

c) I am not aware of any plastic, for general use melting at 60^oC.

d) The answers are from clowns or the question is from a person lacking common sense ?

e) Petes answers looks to be stinky but more often than not i have seen aren't. So gave GA _{where is the GA you promised RVZ ?}

Yes, I am sure that they understood that but there are to many variables to give a definite temperature to answer the question.

Why just plastic if the temperature of the plastic ring has gotten hot enough to cause injury don't you think metal rings would also.

Matter of fact if the temperature inside the shield was hot enough for ether to conduct heat to the face to cause injury by the time they did your face would already be blistered by being exposed to it.

Typical of asking the question BEFORE putting the brain in gear
