Top Shop Tips: Welding Aluminum
Dave learns how to weld aluminum from Lincoln Electric welding instructor Karl Hoes. From Machinery Show 713such high thermal conductivity. You put the heat to it it's a super highway for heat. Aluminum conducts the away. But then ask -- -- gets saturated with -- it changes in the behaves differently so it takes a little getting used to. Karl you mentioned the oxides that build up from the welding that are in the weld itself. What are we talking about their focus really on the aluminum itself aluminum reacts instantly with the air that we breathe. The oxygen in the air combines with the aluminum and it forms a chemical compound on the surface of the aluminum it's called aluminum oxide . In a little relax as would grinding wheels are made out in -- paper you know every -- you see its aluminum accents are very abrasive. Very hard material -- 3700 degrees it melts a thousand degrees hotter that steel. It's a second hardest material known to man as far as a natural occurring material next to diamonds. So here -- this disparity right you have aluminum which has a lower melting temperature -- the steel and aluminum oxide that has a higher melting temperatures. Where that's the challenges that on the backside is actually a form of rocks but it's a tightly and hearing -- and once that surface rust on the aluminum doesn't prosper and that's why don't have to paint aluminum sometimes. Oh that's the kind of hazy it when you first get sent -- -- that shiny bit -- while that out of coming over time that oxide layer grows thicker the problem backside is aluminum oxide actually absorbs things into it. And hydrogen from the air and moisture humidity over time gets you into that oxide and even

Hi welcome to the workshop. I'm mostly electric company we're gonna talk today a little bit about flux core make welding. First of all there's two types of flux well. There's gas shielded flux core welding and herself shielded flux for a while we're going to be talking about which cell shieldedand explosion. Some precautions include -- now well on containers that held flammable . Materials . Do not dwelled on containers with unknown contents. Refer to AWS data or for more information refer to safety and welding and cutting at Lincoln Electric dot com for more information. Remember always read and follow warning labels .

Hi welcome little orders were up. I'm Karl is totally electric while at school I'll. We're gonna talk today a little bit about training where you can do it well tree. Locally you can go through your farmers' groups like the future farmers of America. And go to Community Colleges schools. Nationallyyour farmers' groups like the future farmers of America. And go to Community Colleges schools. Nationally groups like the American welding society -- manufacturers like Lincoln Electric or -- at Lincoln foundation. Could be of great assistance you can actually get information on all of these groups on line by going agriculture dot com slash -- workshop. Well you say when your policy -- rules you must inspect your work area for workplace hazards that may include trip hazards. Sharp objects electrical hazards. Fumes and gases. Come Boston's. Remember inspect your work -- one half hour after welding for possible fires. Refer to safety and welding and cutting at Lincoln Electric dot com for more information.

Karl explains polarity, AC versus DC sitck welding. Also, electrical safety.you're electrode is the negative part of the term. DC positive gives deep penetration good for heavier steel -- structural steel. Painted metals rusty steel DC negative is better for thin material were burned through might be an issue. Welding is safe when you followed a safety rules. Electric -- should be a concern when -- some precautions. Include insulating yourself from the work. Where dry clothing. Maintain electrical equipment -- use a qualified electrician when working on primary vote. Refer to safety and welding and cutting at Lincoln Electric dot com for more information. Remember always read and follow warning labels .

What a little while his workshop on Carl's like electric moments of Cleveland I'll. We're gonna talk about another important welding process today as the gas that are willing process often referred to as a take welding process. Yes constant arc welding is a process used in non consumable andraising. Tig welding as often referred -- materials materials as thin as razor blades can be well. Remember most battles can be while the with the team welding process. You're thinking about purchasing an AC DC machine. You might wanna consider it to change the first welding machine I bought was -- take water and I bought because

Welcome to the welders were shot. I'm Carlos building electric welding school They were gonna talk about our face. Hard facing is using the welding process to deposit a layer of Wear resistant material. Tool machine to expand its service life. There are a lot of benefits to heart facing. can saveme think you can go to Lincoln Electric that common in check products consumables . And go to hard facing and there's a lot of different choices are. Well you say when you followed safety rules. Fumes
