If such a grouping of agencies doesn't presently exist, the sport representative will attempt to bring together all programming agencies presently operating in that sport. Each sport which has membership on the council will designate a director to This will ensure all sport groups receiving available service from their provin- cial sport governing body and from the sports council and guarantee the best use of available resources to amateur sport. Also announced as part of the program was the annual golf tournament to be held at the Elmira Golf Club. Saturday. June 12th.

A weld pool is that put. of the metal an get: melted ud- er the beet from the weld~ hope to find how the shape of the weld pool affects the strength or toughness or other mechanical proper- ties of a weld. - This is the first "eo-op" NRC grant ever awarded a team of UW researchers. The idea is that the three will be able to make faster progress working together on the weld pool problem than any one of them could, working alone. h, The researchers are: Dr. Hugh Kerr, wturis,in- terested in metallurgy and how metals and alloys solidi- fy: Dr. Al Strong, who will bestudying how the metal melted by the heat of the welding are acts, and Dr. Clarke Hermance. who is interested in mathematical models of the way heat is transferred from the melt- ed part of theme to the unmelted part that surrounds it, and of interactions be- tween the welding arc and the metal. An additional H0,000 has been promised by NRC, so the grant will total 860.- 000 over a three year period One of the most import- ant industrial processes is welding ... the joining of metal to metal. It is vital in the building of car frames and oil pipelines, electronic instruments and high rises. Yet welding has remained as much an art as it is a science; much current tech- nology is based on the trial- and-error method. rather than on any Scientific un- derstanding of the process. The intent of the NRC "co-op" grant program is to encourage experts to pool their knowledge. Dr. Kerr has long been interested in fracture me- chanics and "netallurgy, as well as the solidification of metals and alloys: Dr. Strong is broadly interest- ed in ftqid flow problems: Dr. Hermance is particular- ly interested in modelling heat transfer problems, and in developing mathe- matical solutions to such problems. "We feel that by putting together these different kinds of knowledge we can come to some understanding of what takes place when metals are welded." says Dr. Kerr. "By that I mean. some new scientific un- derstanding so we will not only be able to predict mt know whyitllappenS.†. . The weld pool affects the mechanical properties of a weld because it has some-- thing to do with the way the metal crystallizes " it cools again. (Mechanical properties include how strong it is, how likely it is to' crack. how it stands up to temperature changes. andsoforth). Dr. Kerr says the new research was stimulated. in part. by earlier studies by one of his former gradu- ate students, Dr. Scott Law- son. Dr. Lawson had hoped to study how crystals be-. come arranged in welded metal, as the metal solidi- ties, but soon began to realize that to understand the crystal structure bet- ter he needed to understand the shape of the weld pool better. , "We believe shape and size are dependent on the nature of the material. on its thickness.“ the depth of the weld. the' Speed at which the welding is done, the angle at which it is done, and other factors." says Dr. Kerr. “This student, who has gone on to become a welding researcher with Ontario Hydro, came up with results ft? gave as new ideas as how _ we might control the shape of the weld pool. and there- fore ultimately. the meehani- cal properties of the weld. But all this is'in the form of a few hypotheses at the moment; there is no such thing as a mathematical model that explains mat- ters. Thus we are very much in the initial stages. For in- stance, nobody yet under- stands why 'humping' some- times occurs in welding ... that's when the liquid metal solidifies into a series of little bumps instead of into a smooth ridge. "Our first hope will be to extend some of the re- stricted mathematical mod- els which already exist." sayd Dr. Strong. "We hope to get a broader picture as to what happens when you weld widely different types of materials under a great variety of conditions." Initially. many of their ex- periments will involve gas- tungsten arc (GTA) weld- ing, because it is simpler than most. They will be working with a wide variety of metals: carbon and stain- less steels and aluminum. In addition to the gradu- ate student referred to above Dr. Kerr has a student in- vestigating grain structures in carbon steel welds. and another studying crystal structures of stainless steel. In general terms. the long range goals of Kerr. Strong and Hermance. are to op- timize welding practices _.. to make them better. or cheaper or faster. They point out that not only is this research badly need- ed today. it should be a continuing need since new steels and alloys are con- (Commued on page 26)
