There are many sculptors who create their works from metallic materials using welding techniques for assembly. Next, we propose a simple welding practice with which we intend to make you feel like a real sculptor and also learn how to use the TIG welding technique. The proposal consists of making a reproduction of a work by the famous Basque sculptor Jorge Oteiza (Orio, 1908- San Sebastián, 2003); specifically of the work that we reproduce in the following video (replica created by a welding student): However, you can also use any other similar work by the artist, which is part of his so-called Experimental Laboratory, specifically the “small models (…) based on thin metal sheets arranged in experimental families: Vacancy of the sphere, Opening of polyhedra, empty constructions, empty boxes, etc..” These are “minimal and empty sculptures made in 1958-59, in which some, such as the sculptor Richard Serra, have wanted to see a precedent for Minimalism”, as indicated on the Jorge Oteiza Foundation-Museum website. , in Alzuza, Navarra (www.museooteiza.org/). The process to follow is described below.
Measure the dimensions of the sculpture to be reproduced. We intend that the dimensions of the piece once finished are no larger than those of a cube with a side of 100 mm. Therefore, we Belarus Email List choose an image of the sculpture to reproduce and measure as many dimensions as possible. To do this, we can print the image and make the measurements with a simple ruler, or we can import the image into computer-aided drawing software and make the measurements using the program commands, as we can see in the following image: Welding_sculpture_1 Due to the distortion due to the perspective of the image, we observe that the measurements of the main edges differ slightly, although all of them are around 350 mm, so that is the value that we are going to take as valid. From this value we are going to calculate the scale, to adapt the image to our reference cube with an edge of 100 mm: if we consider that the edge of 350 mm is going to be reproduced as 100 mm, the reduction scale is 350/100 = 3.5. That is, we will divide the dimensions that we take in the image by 3.5 and adapt them to our convenience by applying our “artistic” criteria.
Prepare a plan of the pieces that make up each face. It can be done by hand or using a computer-aided drafting program (such as Autocad, DraftSight, Solid Edge, etc.). In these plans we will include the dimensions that will allow us to later trace the pieces on a sheet to be able to manufacture them. welding_sculpture_2 3.- Make a virtual assembly of the sculpture. This step is optional, but it will allow us to detect possible errors. To do this, we carry out 3D modeling of all the pieces that make up our sculpture, using 3-dimensional drawing software, such as Solid Edge. Once the parts are “created”, they are assembled in an assembly type file. welding_sculpture_3 This program has the Key Shot plugin, which allows you to obtain photorealistic renderings of the sets that have been modeled.
