Why are grooved butt joints better for welding thick plates then square butt joints?
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.

What type of joint is found at the shoulder and between the skull plates?
The shoulder joint is a ball and socket joint, allowing a wide range of motion. The joints between the skull plates are fibrous joints known as sutures, which are immovable joints that provide strength and support to the skull.
Are epiphyseal plates cartilaginous joint?
Yes, epiphyseal plates are cartilaginous joints located near the ends of long bones in children that are involved in the process of bone growth and ossification.
Is suture a synovial joint?
No, a suture is not a synovial joint. Sutures are fibrous joints found in the bones of the skull and are immovable, serving to hold the bones together. Synovial joints are movable joints found in the body, characterized by the presence of a synovial capsule and fluid.
Three classifications of joints?
Fibrous joints ( like suture joints, syndesmosis, gomphosis), Primary cartilaginous joints (like cartilage plates in long bone) and secondary cartilaginous joint ( like pubic symphysis), synovial joints ( like shoulder and hip joints).
Is spongy bone filled with cartilage?
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.
What is the Different between TIG arc welding and gas welding?
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
What does 7016 stand for on a welding rod?
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
How much thickness of plates weld by using gas metal arc welding?
See preceding question re: Mig welding.
What type of joint is found at the shoulder and between the skull plates?
The shoulder joint is a ball and socket joint, allowing a wide range of motion. The joints between the skull plates are fibrous joints known as sutures, which are immovable joints that provide strength and support to the skull.
What is the best example of sutures joints?
Probably the best known suture joints are those that join the bone plates of the skull.
How metal pipes are manufactured?
By rolling and welding flat plates or more commonly by the extruding process.
What are joints and bedding plates and how are they different limestone?
Joints are natural fractures in limestone that result from stress in the Earth's crust, while bedding plates are horizontal layers within limestone formed by sediment deposition. Joints are usually vertical or diagonal in orientation, cutting across bedding planes. Bedding plates provide a snapshot of the environment during sedimentation, while joints allow for the movement of fluids through the rock.
What is back step welding?
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.
Advantages and disadvantages of welded joints?
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
Where are the joint found?
Termed "sutures", the occipital, parietal, temporal and frontal plates are sections of the human skull. Separate in infancy, they grow together and become completely joined in early adulthood. They are the seams between the plates.
Why do grounding plates work better in the desert areas?
Grounding plates work better in the desert areas because of the vast land.
Are epiphyseal plates cartilaginous joint?
Yes, epiphyseal plates are cartilaginous joints located near the ends of long bones in children that are involved in the process of bone growth and ossification.
