welding can be a dangerous job if u do not have the right education and knowledge of the machines you use
one of the most dangerous machines in welding is the oxyacetylene torch if not properly set up u could blow up the cylenders and die or be sent to the hospitol with 3rd degre burns all over ur body
A Lot of people that want to do welding are afraid that the jobs are all going to eventually be taken over bye robotic welding machines but that's not going to happen quite yet there are jobs that alot of machines cant do like underwater welding or being out in combat with the military and building hangers and welding trucks and other equipment to fix them
With welding you need to know a lot of math and some science u need to be able to know how much metal you may need to cut or how much fillet rode u need or stick rods or what kind and how thick they must be and with scienc u need to know the metal properties and what may or may not be on the metal incase you have to wear a respirator because of gases and fumes that are given off when welding.
If u want to weld u have to be comfortable with welding in uncomfortable positions and extreme heat. Heat exhaustion is a big factor with welding if u do not stay hydrated u can put yourself in a serious situation especially when you are working on your own
Weldin is a dangrouse job but if you get the right job and stick with it and work every day it can pay off in the long run becouse most welding jobs are dangrous and very complicated and require skilled welders and those companys pay good money for someone that can do the more complicated welding jobs like tig welding and oxy.
