The square butt jointis used primarily for metals that are 3/16 inch or less in thickness. The joint is reasonably strong, but its use is not recommended when the metals are subject to fatigue or impact loads. When you are welding metals greater than 3/16 inch in thickness, it is often necessary to use a grooved butt joint. The purpose of grooving is to give the joint the required strength. When you are using a grooved joint, it is important that the groove angle is sufficient to allow the electrode into the joint; otherwise, the weld will lack penetration and may crack. However, you also should avoid excess beveling because this wastes both weld metal and time. Depending on the thickness of the base metal, the joint is either single-grooved (grooved on one side only) or double-grooved (grooved on both sides). As a welder, you primarily use the single-V and double-V grooved joints.
The shoulder joint is a ball and socket joint. The joints between the skull plates are fused joints (no movement).
No, sutures are where two bones more or less fuse together into one bone.
Fibrous joints: They are held together by fibrous connective tissue and offer little or no movement, such as sutures in the skull. Cartilaginous joints: These are connected by cartilage and allow for limited movement, such as the joints between the vertebrae. Synovial joints: These are the most common type and have a synovial cavity filled with fluid that allows for smooth movement, such as the knee and shoulder joints.
Spongy bone is not filled with cartilage. Spongy bone is composed of trabeculae, which are interconnected plates and rods. Cartilage is a different type of connective tissue that can be found in joints and in the growth plates of bones.
A fixed joint in the skeleton is a type of joint that does not move, providing stability and support to the body. These joints are connected by fibrous tissue or cartilage and allow for minimal to no movement. Examples include the joints between the bones in the skull.
Gas welding basically used for weaker joints(in sheets) and arc welding for stronger one(plates). mobile welding (not in a shop)is the ideal time for arc welding . gas welding is the way to go as far as production is concerned , but requires environment with little air circulation or wind , plus gas bottle , machine , and a short lead , which makes it ideal for shop work answer Gas welding - generally use for welding of thin plates/pipes. Less heat input and less likely to burn off the edge of the plates (undercut). It is a more expensive process because of gas shielding. Arc welding - use for thicker plates usually with larger size electrodes. Higher weld production rate. Shielding by means of electrode coating. Both processes can meet the required mechanical properties usually
No
for steel structure building can i use: -size 2.5mm of 7016 welding rod as a filler for welding IPE240 to plates -size 2.5mm of 7016 welding rod as 2nd pass
See preceding question re: Mig welding.

Probably the best known suture joints are those that join the bone plates of the skull.
By rolling and welding flat plates or more commonly by the extruding process.
Backstep welding is a technique to avoid distortion while welding on thin sheets. In the backstep technique, the general progression of welding may be left to right, but each bead segment is deposited from right to left. As each bead segment is placed, the heated edges expand, which temporarily separates the plates at B. As the heat moves out across the plate to C, expansion along outer edges CD brings the plates back together. This separation is most pronounced as the first bead. With successive beads, the plates expand less and less because of the restraint from the prior welds.
M.I.G.and M.A.G.S.Advantages1) Higher welding speeds2) Greater deposition rates3) Less post welding cleaning (e.g.no slag to chip off weld)4) Better weld pool visibility5) No stub end losses or wasted man hours caused by changing electrodes6) Low skill factor required to operate M.I.G/ M.A.G.Swelding torch7) Positional welding offers no problems when compared to other processes. (Use dip or pulsed mode of transfer)8) The process is easily automated9) No fluxes required in most cases10) Ultra low hydrogen processM.I.G.and M.A.G.S.Disadvantages1) Higher initial setup cost2) Atmosphere surrounding the welding process has to be stable (hence the shielding gasses), therefore this process is limited to draught free conditions3) Higher maintenance costs due to extra electronic components4) The setting of plant variables requires a high skill level5) Less efficient where high duty cycle requirements are necessary6) Radiation effects are more severe

Grounding plates work better in the desert areas because of the vast land.
