PLAN No. 1146. METALLIC FURNITURE
Extensive use of oxy-acetylene welding is made in the manufacture of metallic furniture and in kindred trades. Welding is an efficient and economical way of joining various parts together, as well as of making the parts themselves. The work may be more or less routine and much of it is done at the bench. This is a comparatively easy type of welding, in which a man can become proficient in a short time. It would be eminently suited to the welder who has trouble in going about or who is easily fatigued, and who would be better off in some sedentary work. The process is largely used in the manufacture of steel desks, chairs, filing cabinets, office safes, stepladders, and surgical, hospital and dental furniture.
PLAN No. 1147. CONTAINERS
Welding is fast superseding old methods in the manufacture of containers of various kinds out of sheet metal. In this class is included the manufacture of steel barrels, range boilers, kitchen utensils, light air tanks, and storage tanks. This kind of work needs a well-trained man on the job. Except in the case of larger objects, the work can be done at the welding table, and it is not of a straining nature.
PLAN No. 1148. METAL PLATE
Metal plate welding is quite similar in its scope to sheet metal work. It is largely used in the manufacture of ammonia and air receivers, vacuum driers, steam driers, and vats. The process is not used in boiler work to any extent, as the consequences of a faulty weld might be extremely serious.
PLAN No. 1149. FOUNDRIES
In steel foundries the process is extensively used in cutting away risers, gates, and heads from castings. As compared with the old method of cutting with a saw, the gas process is much quicker and much more economical. This sort of cutting work is simple and does not require great dexterity. The welder should be capable of bending over or assuming more or less cramping positions, as he has to work on the castings in positions in which they have been left on the floor. Welding is almost universally used in the reclamation of defective castings, and by this process castings are saved which for some slight defect would have been consigned to the scrap heap. The process finds application also in the welding of blowholes, cold shuts, porous spots, and cracks. It is used to some extent in manufacture, two parts being cast separately and joined by welding.
