A greatmany results of comparative tests have re-cently been published, but it is not easy toform any reliable conclusion from these,owing to the variable conditions involved,coupled with the fact that these resultsare inevitably somewhat colored by a lean-ing towards one or other system on thepart of the investigator. The general im-pression, however, which is conveyed bythese tests arid confirmed by personal ex-perience, is that for speed of in welding straight or simple seamsin iron or steel plates, the oxy-acetyleneprocess is unrivalled up to a thickness of% inch. For thicknesses of % inch to YKinch there is not much to i;the two methods, and above \i, inch thick-ness of plate, conditions favor arc is important, howi in con- nection with arc welding, that tothe best resu
