摘要： PURPOSE:To improve the finishing precision and quality by carrying out the automatic grinding work and obtaining an always uniform ground surface, as for an automatic grinding device used for the grinding of the excess metal part of a welded coupling made of steel. CONSTITUTION:A grinder 2 on which a grinding wheel is installed is fixed in an arbitrary tilt angle by a clamp lever, and mounted on a longitudinal tilt slide 6. Since a longitudinal tilt mechanism which is position-controllable during grinding is installed, the contact angle of the grinding wheel can be controlled arbitrarily, and the crushing and clogging are prevented. Further, a vertical mechanism which can control the vertical shift and positioning is installed so that the pressing force obtained from a load cell 9 becomes always constant, according to the unevenness of a ground surface or in order to control the grinding quantity. A traveling truck 18 is arranged in parallel to a welding line, and carries out grinding, traveling forward or rearward on a rail 20 fixed by a magnet 19.

摘要： PURPOSE:To subject a bond part to the formation of the finer grains after recrystallization and to improve toughness by subjecting base metals to welding of the 2nd pass at a specific distance from the center line of the weld metal of the 1st pass and further to welding of the 3rd pass at a specific distance from the center line of the weld metal of the 1st pass. CONSTITUTION:The groove part of the base metals 1, 1 consisting of low alloy or resembling component steels is subjected to electron beam welding to form the weld metal 2A of the 1st pass. The position apart by 2H from the center line of the weld metal 2A is then subjected to the electron beam welding under the same conditions to form the weld metal 2B of the 2nd pass. The H which is the reference for the spacing between the welding pass positions is the distance between the region where the weld heat affected part is subjected to the formation of the finer grains after the recrystallization and the bond part. Further, the position apart by H in the same direction as the direction of the 2nd pass from the center line of the weld metal 2A of the 1st pass is subjected to the electron beam welding under the same conditions to form the weld metal 3C of the 3rd pass. The coarser grains are formed in the bond 3 part of the 1st pass and the 2nd pass and the finer grains are formed after the recrystallization by the heat cycle arising from the welding of the 3rd pass. The toughness is thereby improved.

摘要： PURPOSE:To stabilize an arc and to improve the toughness of weld metal by using a pulse power source having the specific number of pulses and using shielding gas with a low mixing ratio of CO2 and O2. CONSTITUTION:The pulse power source 1 having a pulse generator 2 with the number of pulses 300-1000pps is provided and a welding bed 3 and a bomb 9 for the shielding gas such as CO2, Ar, etc., are arranged. The shielding gas is supplied from the shielding gas bomb 9 to the welding bed 3 by regulating its pressure and flow rate by a regulator 7 and a current impressed with a pulse from the power source 1 is conducted to the welding bed 3 and an object 10 to be welded and a wire 6 is fed to the welding bed 3 to perform the welding. Since the energy density becomes high by taking in the pulse, even if the mixing ratio of CO2 and O2 is low, the arc is stabilized. Further, since the contents of N and O in the weld metal are reduced, the toughness of the weld metal is improved.

摘要： PROBLEM TO BE SOLVED: To improve the mutual joint strength of dissimilar metal materials.SOLUTION: In a dissimilar material joint structure that joins together an anti-vibration member (first member) 14 and a joint member (second member) 15 which is formed of a dissimilar metal material to the anti-vibration member 14, the anti-vibration member 14 is sandwiched by a plurality of joint members 151 and 152, and these respective joint members 151 and 152 are joined together by welding. Due to contraction of a weld material 153 welding the joint members 151 and 152, the anti-vibration member 14 is sandwiched between the joint members 151 and 152, whereby the anti-vibration member 14 and the joint member 15 are joined. Consequently, a thermal treatment for welding the dissimilar metal materials becomes unnecessary, and the welding operation can be carried out easily. Moreover, since the anti-vibration member 14 is sandwiched between the joint member 151 and the joint member 152 by the contraction of the welding material 153, the mutual joint strength of the anti-vibration member 14 and the joint member 15 which are the dissimilar metal materials can be improved.
摘要翻译：要解决的问题：提高异种金属材料的相互接合强度。解决方案：在防振构件（第一构件）14和由异种金属材料形成的接合构件（第二构件）15连接到防振构件14上的不同材料接合结构中，防振构件14被多个接头构件151和152夹持，并且这些各个接合构件151和152通过焊接接合在一起。由于焊接材料153的收缩焊接接头构件151和152，防振构件14被夹在接头构件151和152之间，由此防振构件14和接头构件15接合。因此，不需要用于焊接异种金属材料的热处理，并且可以容易地进行焊接操作。此外，由于通过焊接材料153的收缩将防振构件14夹在接头构件151和接头构件152之间，所以防振构件14和接头构件15的相互接合强度是不相似的可以改善金属材料。版权所有（C）2012，JPO＆INPIT

摘要： PURPOSE:To make a porous material uniformly dense without cracking by irradiating the porous material with laser light to melt the surface and to seal the pores in the surface and by subjecting the material to hot isostatic pressing. CONSTITUTION:A porous material 1 having many pores 2 is irradiated with laser light 5 through a condenser 4 to melt the surface of the material 1 and to form a very thin surface layer 3. By moving the laser light 5 in the direction of an arrow 6, the layer 3 is extended over the entire surface of the material 1 and the pores 2 in the surface are sealed. The material 1 is then put in an HIP device 8 and heated to a high temp. with a heater 7 and a pressure 10 of gas is applied with a gas compressor 9. Since the three-dimensional uniform pressure can be applied to the entire porous material 1, the pores 2 are sealed and a dense material is obtd.
