Show OXY oxyacetylene ACETYLENE WELDING each year adds new features and accomplishments ments to the oxyacetylene oxy acetylene system of welding and steel cutting says the anaconda IToi mont it standard As operators become more accustomed to handling tile the varied and nd often exceptionally difficult lines of 0 work they are constantly called upon to perform the limit of its use is found to be constantly extending engineers are working on and producing more efficient apparatus as demand for finer and better work increases and as a result very few breakages break ages occur that cannot be successfully handled ten years ago very little could be successfully cess fully welded with the oxyacetylene oxy acetylene torch five years ago practically no headway had been made in welding though some steel cutting operations had been performed but during the past five years there have been installed in the state of montana over seventy welding and steel cutting plants demand for larger and better equipment proves the exceptional value of this system to tile the public and to large mining railway and construction companies whose losses are enormous when breakages break ages of machinery occur on account of delays in operation these delays are very largely eliminated through quick and permanent repairs made with the oxy acetylene torch through force of habit many people even good and up to date mechanics do not realize the class of work that can be done small casting made of iron steel aluminum brass and bronze wrought steel and drawn copper machine parts such as engines cylinders crank cases manifolds frames tor tion tubes hangers braces bearings etc either worn cracked or broken in every conceivable cei vable manner are very easily and satisfactorily facto rily welded large castings in steel and iron such as mining compressor frames cylinders controlling arms fly wheels belt wheels gears etc even though they run into tons in weight with breaks yards in length are welded gel ded quickly and with perfect results the process is increasing in use in navy yards and railway shops where heavy welding and cutting are required flat spots are being built in locomotive wheels caused by slipping when breaks are set main frames of locomotives are being welded and worn spots filled in cylinder castings are being welded firebox sheets are being repaired by welding the shrinkage and aad strain cracks and the cutting torch plays an exceptionally important part in cutti cutting ng out fireboxes fire boxes that are to too 0 badly burned for repair also for scrapping the steel wrecking crews are using the cutting torch for disentangling the twisted steel of the present all steel cars these repairs not only mean the saving of new parts but also the increased service and efficiency in quickly replacing in service such equip m ent atwould as would other otherwise wise be beut out ot 0 commission waiting for and for extended periods parts by older wid and the replacing of new more crude methods and acetylene gases the use of oxygen factor in in is fast b becoming a gigantic creasing the producing capacity of mankind accelerated motion of 0 and in the constantly tile the great wheel of commerce |
