WELDING SYMBOLS

TYPES OF WELDING SYMBOLS     TYPES OF JOINTS By mean so welding, it is possible to make continuous, load bearing joints between the members of a structure. A variety of joints is used in structural steel work and they can be classified into four basic configurations namely , Lap joint,Tee joint, Butt joint and Corner joint.       For lap joints, the ends of two members are overlapped and for butt joints, the two members are placed end to end, The T joints form a Tee and in Corner joints, the ends ae joined like the letter L. Most common joints are made up of fillet weld or the butt also called groove weld. Plug and slot welds are not generally used in structural steel work. Fillet welds are suitable for lab joints and Tee joints and groove welds for butt and corner joints. Butt welds can be of complete penetration or incomplete penetration depending upon whether the penetration is complete through the thickness or partial. Generally a description of welded joints re

AUTOCAD COMMANDS LIST

AUTOCAD COMMANDS LIST WITH EXAMPLE Here I will show autocad commands list with some example used in making drawing by using  auto cad, autocad stands for computer aided design,many student those who completed there civil engineer but they do not know auto cad commands and they face some problems while drawing typical plans. Autcad is basic software for a civil engineer that he should must know about it and with some most useful commands. After completing engineer many students face problems for getting jobs, they ask that there is no job in civil engineering or they sir I am not getting job or just they go for site engineer job. Civil Engineers has more scope in there field for there career if they knew some software's and some technical knowledge. AUTOCAD COMMANDS LIST First I will show the commands which I use mostly or repeatedly 1)   Line       ( L enter) 2) Offset   (O enter ) 3) Trim  (TR enter enter) 4)  Move  (M enter) 5) Copy

FILLET WELD

WHAT IS FILLET WELD AND ITS PROCESS     Weld is the process of joining two pieces of metal by creating a strong metallurgical bond between them by heating or pressure or both. It is distinguished from other forms of mechanical connections. Such as riveting or bolting, which are formed by friction or mechanical interlocking. It is one f the oldest and reliable methods of joining.      Welding offers many advantages over bolting and riveting. Welding enables direct transfer of  stress between members eliminating gusset and splice plates necessary for bolted structures. Hence,     the weight of the joint in minimum.   In the case of tension members, the absence of holes improves the efficient of the section. It involves less fabrication cost compared to other methods due to handling of fewer parts and elimination of operations like drilling, punching etc. and consequently less labor leading to economy. Welding offers air tight and water tight joining and hence is ideal   for
