How to make a double miter corner joint

double miter corner joint is an aesthetic connection. therefore, it is mainly used in designs that require a high degree of sophistication. in addition to the double miter corner joint method, there are other connection methods to ensure durability, but of course their external design is not too beautiful.

double miter corner joint

this method is implemented as follows:

this connection method is commonly used for round pipes. for a successful connection, we need to prepare the following tools and equipment in advance:

• a pipe with diameter of 75 mm and length of at least 1000 mm;
• saw pendulum with a rotary table;
• detachable clamp;
• tape measure
• markers and metal plates;
• electric or gas welding equipment;
• flat horizontal surface.

steps to perform double angle joint

for this work, mastery of special skills is not required, but all marking and measuring manipulations must be done with care and precision.

step 1. we put the pipe on the table of the saw pendulum, measure the required length with a tape measure, put the marker on the marker, clamp the workpiece with a clamp and saw off the first part of the pipe. repeat this operation two more times and get three pipe blanks with a diameter of 75 mm and a length of 300 mm. in other cases, the size may be arbitrary.

 

step 2. you rotate the table of the saw pendulum 45 degrees and fix it in this position.

step 3. fix each of the three pipe segments on the table of the saw pendulum with a fixed rotation and make a cut from one end that will be exactly 45 degrees.

 

step 4. without changing the position of the tube gaps after the first cut, at the ends we mentally draw the longitudinal and transverse diameters, noting their intersection with the tube body with strokes with a marker pen .

step 5. weaken the fastening of the tube on the table of the pendulum and, without changing the vertical position, turn a quarter of a circle or 90 degrees clockwise and correct the workpiece by checking for the absence of fluid. vertical transfer by flat metal plate.

step 6. we make one more final cut with the finished cut. the result is a complex configuration - the result of the interaction of the flat disc of the pendulum saw and the cylindrical surface of the pipe. we bear all three pipe blanks for this operation.

 

step7. we place two blanks on a horizontal surface with the cuts together and bring them together until they touch the desired line. if the marking is correct and the cuts are made efficiently, the blanks form a flat angle exactly equal to 90 degrees.

step 8. without changing the position of the drum tubes, we take them from the inside by electric or gas welding, thus fixing them relative to each other.

step9. only left, at the junction of two horizontally arranged pipes, to attach a third element vertically from the top. if its marking and segmentation are done correctly, the upper workpiece with all its endpoints will perfectly coincide with its intended position.

finally. to eliminate injury and damage, it is necessary to use personal protective equipment: gloves and a welding mask.

like many great businesses, swiss tech began in a garage. the year was 1990, and lothar schreiner  had decided to take his decade of experience in the food processing industry and strike out on his own. with a commitment to hard work, honesty and customer service, swiss tech s. has steadily grown and is currently the largest employer of sanitary welders in west germany. in order to offer its customers in the food, beverage, and pharmaceutical industries a complete range of coverage the company supports a large staff including mobile crews, project managers, engineers, and administrative support.
