The Hazards of Welding Aluminium Breathing in fume containing aluminium, while not wearing a respirator, can lead to irritation of the respiratory system.
Moreover, Can Aluminium be welded?
You can weld aluminum to most other metals relatively easily via adhesive bonding or mechanical fastening. However, in order to weld aluminum to steel, special techniques are required. To avoid this, you must isolate the other metal from the molten aluminum during the arc welding process.
Secondly, What type of welding is best for aluminum?

Simply so, Should you wear a respirator when welding?
Welders should select a respirator recommended for welding. Certain lung or heart conditions can make respirator use dangerous. The OSHA standard requires fit testing for all tight-fitting respirators. Whether you select a maintenance-free or a reusable respirator, the wearer must obtain a satisfactory fit.
Can welding be done on Aluminium?
Aluminum can be welded using a gas-fed torch, but this method is more difficult than MIG and TIG welding. Torch welding of aluminum requires a dexterous welder who can adequately control the torch and the filler rod.

MIG welding is best for thinner gauges of aluminum sheets because of the amount of heat needed. When choosing a shielding gas, 100 percent argon is best for MIG welding aluminum. The welder must choose a welding wire or rod that has an alloy as similar to that of the work pieces as possible to create a quality weld.
When employees must work in environments with insufficient oxygen or where harmful dusts, fogs, smokes, mists, fumes, gases, vapors, or sprays are present, they need respirators. These health hazards may cause cancer, lung impairment, other diseases, or death.
When spray painting, it’s recommended that you wear a paint respirator. Respirator masks prevent many microscopic and scent-free particles from entering your airways during painting and renovation projects. Respirators offer protection against chemicals, harmful vapors and mold spores.
Nearly all aluminum work that is done is between $70-$90 an hour. If they were estimating the prep work(removing wires,foam,anything)then maybe I could see $200. A crack in the bottom of a hull needs welded and patched to be done properly.
Aluminum welding may generate fumes consisting of fluorine, arsenic, copper, silicon, and beryllium (NIOSH 1975h and American Welding Society 1974, both as cited in ACGIH 1986/Ex. Excessive exposure to welding fume can cause a variety of disorders, most notably metal fume fever.Jan 19, 1989
Can anyone wear a respirator mask? Breathing through a respirator is harder than breathing in open air. People with lung diseases such as asthma or emphysema, elderly people, and others may have trouble breathing. Some people with claustrophobia may not be able to wear a mask or hooded respirator.

What are the different classes of respirators? The two main types are air-purifying respirators (APRs) and supplied-air respirators (SARs). Air-purifying respirators can remove contaminants in the air that you breathe by filtering out particulates (e.g., dusts, metal fumes, mists, etc.).
Respirator Extended Use Recommendations Workers in other industries routinely use N95 respirators for several hours uninterrupted. Experience in these settings indicates that respirators can function within their design specifications for 8 hours of continuous or intermittent use.
Aluminum is very susceptible to crater cracking, therefore, craters should be filled in so that failure does not occur at the end of a weld. Aluminum also requires different pre-weld and post-weld processing. Aluminum forms an oxide layer that has a higher melting temperature than the actual aluminum itself.
Aluminum doesn’t act the way other metals do during welding, so it can be difficult to determine weld progress and quality. Simply put, aluminum is difficult to weld because it is a soft, highly sensitive metal insulated by a tougher oxidized layer.
